I had an old boss who was working with tape-reel cartridges when he was younger. He had an alternate word for what we use as "bug". Frog.

They were based in Louisiana, and often had the windows open because of the heat. One afternoon, a frog managed to jump straight through the window and landed directly in between a tape-reel and the spindle, instantly crushing the frog, ruining the wheel, and destroying the data on the real.
